6.1: The Laplace Transform - Mathematics LibreTexts

WebIn mathematics, the Laplace transform, named after its discoverer Pierre-Simon Laplace ( / ləˈplɑːs / ), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex frequency domain, also known as s-domain, or s-plane ). WebJul 14, 2024 · As requested by OP in the comment section, I am writing this answer to demonstrate how to calculate inverse Laplace transform directly from Mellin's inversion formula. It is known that for a &gt; 0 if f ( t) = t a − 1 then F ( s) = Γ ( a) / s a. Now we are going to verify this result using Mellin's inversion formula.
